[Treatment, follow-up and prognosis of drug addiction (author's transl)].

Using a standardised psychological questionnaire (self-estimation scale, personality-inventory FPI of Fahrenberg and Selg) and serial examinations, the effectiveness of a therapeutic concept combining drug, environmental and group therapy was tested. The psychological parameters objectified stabilisation of the psychological-autonomic and emotional areas as well as ego functions. The follow-up study extended over an average of five years and included 101 former drug addicts (14 could not be interviewed, 10 had died). Social stability was observed in 63% (satisfactory working performance, reduction of sexual problems, contacts with friends). 36% of the group had abstained from further drug taking, 27% were taking them periodically, 32% had to be treated again and 5% had deteriorated (trend towards invalidism).
